This little module is perfect. It easily hooks up to my BRS RODI unit and tells me exactly what my TDS is for my water supply coming in and for my RODI water coming out. Easily tells you when its time to change the filters and resin in your RODI unit. A MUST HAVE

Installation real easy and works great. Should have gotten this when I first started using RO system. Much better than a TDS meter I been using for months.

Great Little Tool!By Johnon 11/28/2012

An amazing little device!! Its nice to be able to see how much the RO/DI system is actually doing! I had no idea my TDS were so high, and at the end... 0 TDS :) Very simple to hook up. I even moved it to a couple different points in the system to see the difference. I would defiantly recommend this to any reefer!
